cement mill outlet temperature formula

Quality, Mill, Simulation, Uncertainty, PID, Robustness . 1 Introduction . Historically, advanced process control efforts in cement products quality have focused on raw meal homogeneity as it is the main factor influencing the clinker activity [1]. Primarily the control and regulation is performed in the raw mill outlet.

The material is then heated to temperature of nearly 1400 °C to 1500 °C when it gets fused together. The fused product is known as the clinkers or raw cement. The size of clinkers varies from 3mm to 20mm and they are very hot when they come out of burning zone of kiln. The clinker temperature at the outlet of kiln is nearly 1000 °C. A rotary .

Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement .

The cement temperature is not allowed to go beyond 100°C otherwise the gypsum, an additive to cement, will dehydrate. The cooling of cement inside the mill is achieved by air and water injection maintaining the dew point of exhaust gas at 50–60°C.

cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.

In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the industry have .
